Add version footer and disable map scroll wheel zoom

- Add build-time version generation script that captures git commit info
- Create /api/version endpoint to serve version data
- Add version footer component showing commit SHA, date, and branch
- Link version SHA to commit on git.deco.sh for easy navigation
- Fix footer text duplication issue with i18n translations
- Disable mouse wheel zoom on map, require +/- buttons for better UX
- Update service worker cache to v4 with new version-footer.js
